A ΣΔ DAC is similar to a ΣΔ ADC, except that the noise shaping in the DAC is performed using a digital modulator rather than an analogue modulator. The basic architecture of a one-bit ΣΔ DAC is shown in Figure 8.13. Sign in to download full-size image Figure 8.13. One-bit ...

in the early 19th century irreversibly deprived culture of this intuition, leading to a situation where the formal aspect of architecture became a game of discourses: "The incomplete, unrecognizable patterns, up and down every street, become a kind of noise and the bubble of symbolic messages"....
The operation of the proposed structure is similar to the first order modulator except for its quantizer that is realized by a SAR ADC. Also, it has a simple loop filter topology so that only a Finite Impulse Response (FIR) filter is used to provide the first-order noise shaping. Due to...
The proposed NS SAR ADC adopts extra one passive feed-forward path summing in realizing second-order noise shaping with the minimum modification to a standard SAR. Compared with previous works, the noise sources of residue sampling and first-order integration on filter capacitors are obviated. It...
The concept of noise shaping is best explained in the frequency domain by considering the simple ΣΔ modulator model in Figure 4.3.17. Sign in to download full-size image Figure 4.3.17. Simplified frequency domain linearized model of a sigma-delta modulator. The integrator in the modulator ...
